为什么？

setGeometry: Unable to set geometry 22x22+320+145 on QWidgetWindow/'WidgetClassWindow'. Resulting geometry:  116x22+320+145 (frame: 8, 30, 8, 8, custom margin: 0, 0, 0, 0, minimum size: 22x22, maximum size: 16777215x16777215).

该项目是:

project.pro

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = untitled5
TEMPLATE = app


SOURCES += main.cpp\
        widget.cpp

HEADERS  += widget.h

widget.h

#ifndef WIDGET_H
#define WIDGET_H

#include <QWidget>

class Widget : public QWidget
{
    Q_OBJECT

public:
    explicit Widget(QWidget *parent = 0);
    ~Widget();

private:
};

#endif // WIDGET_H

widget.cpp …
